Damn. We’re already at almost 10000 qubits with a sustained exponential growth. Ten more years seems about right.

RSA-2048: ~4096 logical qubits, 20-30 million physical qubits

256-bit ECC: ~2330 logical qubits, 12-15 million physical qubits

RSA-3072: ~6000 logical qubits, 30-40 million physical qubits
